The fastest way depends on your printer type and what's already plugged in

Most printers connect in one of three ways: USB cable plugged directly into your computer, wireless over your home WiFi network, or through a network cable if you're in an office. Before you start, find your printer's model number — it's usually on a sticker on the back or bottom — because you'll need the right software to make it work.

Windows and Mac both have built-in printer detection that works for many newer printers, but older models and some wireless printers need you to install software first. The steps are slightly different depending on your setup, so read the section that matches what you have.

Key Takeaways

  • USB printers are the simplest: plug the cable in, and Windows or Mac usually finds it automatically within a few seconds.
  • Wireless printers need to be on the same WiFi network as your computer, and you may need to install software from the printer manufacturer's website first.
  • If your printer doesn't show up after plugging it in or connecting to WiFi, download the driver software using your printer's model number.
  • Once added, test the connection by printing a document or the printer's test page to confirm everything is working.

Adding a USB printer on Windows

Plug the USB cable from your printer into an available USB port on your computer. Windows will detect it within 5 to 10 seconds — you'll see a notification in the bottom right corner of your screen. If Windows recognizes the printer, it will install basic drivers automatically and you're done.

If nothing happens after 30 seconds, or if you see an error message, you need to install the printer software manually. Go to the printer manufacturer's website (Canon, HP, Epson, Brother, Xerox, and others all have support pages), find your exact printer model, and download the driver software for Windows. Run the installer, plug the printer in when it asks, and follow the on-screen steps.

To check if your printer is ready, go to Settings > Devices > Printers & Scanners. Your printer should be listed there. If it is, you can print a test page by clicking on it and selecting Print a test page.

Adding a USB printer on Mac

Plug the USB cable in and wait 10 to 15 seconds. Mac will usually find the printer and add it automatically — you'll see a notification at the top of the screen. Open System Settings > Printers & Scanners and look for your printer in the list.

If your printer doesn't appear, download the software from the manufacturer's website using your printer model number. Most Mac printer software comes as a .dmg file — double-click it, follow the installer, and plug the printer in when prompted. After installation, go back to Printers & Scanners and click the + button to add it manually.

Once it's listed, select it and click Print Test Page to confirm it's working. If the test page prints, you're ready to use it with any program on your Mac.

Adding a wireless printer on Windows

Turn on your printer and make sure it's within range of your WiFi router. Most printers have a WiFi button or a menu screen where you can see available networks. Connect the printer to your home WiFi network using its control panel — the printer will ask for your WiFi password, which you enter using its buttons or touchscreen.

Once the printer is connected to WiFi, go to your Windows computer and open Settings > Devices > Printers & Scanners. Click Add a printer or scanner. Windows will search for printers on your network and should find yours within 30 seconds. Click on it and select Add device.

If Windows doesn't find it, download the printer software from the manufacturer's website first, then try adding it again. Some wireless printers need their software installed before Windows can see them on the network. After it's added, print a test page to make sure the connection is stable.

Adding a wireless printer on Mac

Connect your printer to WiFi using its control panel or touchscreen, just as you would on Windows. Make sure the printer is on and within range of your router.

On your Mac, go to System Settings > Printers & Scanners and click the + button. Mac will search for available printers on your network. When you see your printer in the list, click it and select Add. Mac will install the basic drivers automatically for most modern printers.

If your printer doesn't appear in the search, download the manufacturer's software first using your printer model number. After installation, try adding it again through Printers & Scanners. Once it's added, print a test page to confirm it's working.

What to do if your printer won't show up

The most common reason a printer doesn't appear is that the software isn't installed. Before troubleshooting anything else, go to the printer manufacturer's website, find your exact model number, download the driver software for your operating system, and run the installer. This solves the problem in about 80 percent of cases.

For wireless printers, make sure the printer and computer are on the same WiFi network. If your printer is on a guest network and your computer is on the main network, they won't see each other. Check your printer's WiFi settings and reconnect it to the correct network if needed.

If you've installed the software and the printer is on the correct network but still doesn't show up, restart both your computer and your printer. Turn off the printer completely, wait 30 seconds, and turn it back on. Then restart your computer. This clears temporary connection problems that prevent detection.

If the printer still doesn't appear after restarting, uninstall the printer software completely, restart your computer, then download and reinstall the software fresh from the manufacturer's website. Corrupted software files are the second most common cause of connection problems.

Testing your printer and fixing common printing problems

Once your printer shows up in your printer list, print a test page to confirm it's working. On Windows, go to Settings > Devices > Printers & Scanners, click your printer, and select Print a test page. On Mac, go to System Settings > Printers & Scanners, select your printer, and click Print Test Page.

If the test page prints, your printer is ready to use with any program. If nothing prints, check that the printer has paper and toner or ink, and that it's turned on and not showing an error light. If it still doesn't print, restart the printer and try the test page again.

If you can see the printer in your list but documents won't print from specific programs, the program may not have permission to use the printer. Try printing from a different program like Notepad or Word to narrow down whether the problem is the printer or the program. If other programs print fine, the issue is with that specific program's settings, not your printer connection.

Frequently Asked Questions

Do I need to install software if Windows or Mac finds my printer automatically?

Not always. If your printer prints a test page successfully without any software installed, you don't need to install anything else. However, if you want to use advanced features like double-sided printing, color correction, or scanning, you'll need the full software from the manufacturer. Basic printing works without it.

Can I use the same printer on both my Windows computer and my Mac?

Yes, if it's a wireless printer on the same network. Both computers will see it and can print to it. If it's a USB printer, you can only connect it to one computer at a time unless you use a USB switch box, which lets you toggle the cable between devices.

Why does my wireless printer keep disconnecting?

Wireless printers drop off the network when they're too far from the router, when the router restarts, or when the printer goes to sleep. Move the printer closer to your router if possible, and check your printer's settings to disable sleep mode. If it keeps disconnecting, restart both the printer and your router.

What if I lost the software CD that came with my printer?

You don't need the CD. Go to the printer manufacturer's website, search for your printer model number, and download the latest software directly. The downloaded version is usually newer than what was on the CD anyway.

Can I print wirelessly if my printer is plugged in with a USB cable?

No. A USB connection is wired only. If you want wireless printing, you need either a printer with built-in WiFi or a network printer. Some printers have both USB and WiFi options, so check your printer's specifications to see what it supports.
